  • Easiest way to submit data via PHP?

    - by Abijah
    I'm new to PHP, and have spent 10 hours trying to figure this problem out. The goal is to take all data entered into this order form, and send it to my email via PHP. I have 2 questions: 1. I can get PHP to send data from a single menu item (example: Mexican Tortas), but how do I get PHP to send data from multiple items (example: Mexican Tortas, Fish Sandwich and Hamburger)? 2. How do I tell PHP to not send data from menu items that don't have the "How Many?" or "Customize It?" text fields filled out? If you could provide a super simple example (or a link to a learning resource) I would really appreciate it. Thank you, Abijah PHP <?php if(isset($_POST['submit'])) { $to = "[email protected]"; $subject = "New Order"; $name_field = $_POST['name']; $phone_field = $_POST['phone']; $item = $_POST['item']; $quantity = $_POST['quantity']; $customize = $_POST['customize']; } $body = "Name: $name_field\nPhone: $phone_field\n\nItem: $item\nQuantity: $quantity\nCustomize: $customize"; echo "Data has been submitted to $to!"; mail($to, $subject, $body); ?> HTML <form action="neworder.php" method="POST"> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/mexicantortas.jpg"> <h1>Mexican Torta - $8.50</h1> <input name="item" type="hidden" value="Mexican Torta"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/fishsandwich.jpg"> <h1>Fish Sandwich - $8.50</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class ="item"> <img style="float:left; margin-right:15px; border:1px Solid #000; width:200px; height:155px;" src="images/hamburgers.jpg"> <h1>Hamburger w/ Fries - $7.00</h1> <input name="item" type="hidden" value="Fish Sandwich"/> <h2>How Many? <font color="#999999">Ex: 1, 2, 3...?</font></h2> <input name="quantity" type="text"/> <h3>Customize It? <font color="#999999">Ex: No Lettuce, Extra Cheese...</font></h3> <textarea name="customize"/></textarea> </div><!-- ITEM_LEFT --> <div class="horizontal_form"> <div class="form"> <h2>Place Your Order Now: <font size="3"><font color="#037B41">Fill in the form below, and we'll call you when your food is ready to be picked up...</font></font></h2> <p class="name"> <input type="text" name="name" id="name" style="text-align:center;" onClick="this.value='';" value="Enter your name"/> </p> <p class="phone"> <input type="text" name="phone" id="phone" style="text-align:center;" onClick="this.value='';" value="Enter your phone #"/> </p> <p class="submit"> <input type="submit" value="Place Order" name="submit"/> </p> </div><!-- FORM --> </div><!-- HORIZONTAL_FORM --> </form>

  • What should I name instances of a twisted.internet.defer.Deferred?

    - by slacy
    I'm writing code using Twisted, and having trouble coming up with a sensible variable name for my twisted internet deferred's. Here are my candidates: d : Too generic, too short, violates pylint rule C0103. def : Conflicts with function defintion builtin. defer : Conflicts with module twisted.internet.defer deferred : OK but pretty long cb : Still too short, violates pylint C0103, conflicts with many callback method names. cback : Too Weird? callback : Conflicts with method Deferred.callback() I'm looking for other suggestions. It seems like most of the Twisted example code uses "d" which is fine for simple invocations, but when you're passing Deferred's around to methods and storing them as member variables, it's really far too descriptive.

  • jQuery selector to target any CSS name (of multiple present) starting with a prefix?

    - by John K
    I'm considering one selection statement that would target one of many css class names in a single class attribute value based on a string prefix. For example, I want any detail- prefixed class names to get targeted from the following sample links. <a href="eg.html" class="detail-1 pinkify another"> <a href="eg.html" class="something detail-55 minded"> <a href="eg.html" class="swing narrow detail-Z"> <a href="eg.html" class="swing narrow detail-Z detail-88 detail-A"> It's reminiscent of how [class|="detail"] prefix selector works on a scalar attribute value, and also of .hasClass(className), but my question needs both concepts applied simultaneously. Note: The detail- prefix won't necessarily be the first class name of the bunch.

  • How does the CLR (.NET) internally allocate and pass around custom value types (structs)?

    - by stakx
    Question: Do all CLR value types, including user-defined structs, live on the evaluation stack exclusively, meaning that they will never need to be reclaimed by the garbage-collector, or are there cases where they are garbage-collected? Background: I have previously asked a question on SO about the impact that a fluent interface has on the runtime performance of a .NET application. I was particuarly worried that creating a large number of very short-lived temporary objects would negatively affect runtime performance through more frequent garbage-collection. Now it has occured to me that if I declared those temporary objects' types as struct (ie. as user-defined value types) instead of class, the garbage collector might not be involved at all if it turns out that all value types live exclusively on the evaluation stack. What I've found out so far: I did a brief experiment to see what the differences are in the CIL generated for user-defined value types and reference types. This is my C# code: struct SomeValueType { public int X; } class SomeReferenceType { public int X; } . . static void TryValueType(SomeValueType vt) { ... } static void TryReferenceType(SomeReferenceType rt) { ... } . . var vt = new SomeValueType { X = 1 }; var rt = new SomeReferenceType { X = 2 }; TryValueType(vt); TryReferenceType(rt); And this is the CIL generated for the last four lines of code: .locals init ( [0] valuetype SomeValueType vt, [1] class SomeReferenceType rt, [2] valuetype SomeValueType <>g__initLocal0, // [3] class SomeReferenceType <>g__initLocal1, // why are these generated? [4] valuetype SomeValueType CS$0$0000 // ) L_0000: ldloca.s CS$0$0000 L_0002: initobj SomeValueType // no newobj required, instance already allocated L_0008: ldloc.s CS$0$0000 L_000a: stloc.2 L_000b: ldloca.s <>g__initLocal0 L_000d: ldc.i4.1 L_000e: stfld int32 SomeValueType::X L_0013: ldloc.2 L_0014: stloc.0 L_0015: newobj instance void SomeReferenceType::.ctor() L_001a: stloc.3 L_001b: ldloc.3 L_001c: ldc.i4.2 L_001d: stfld int32 SomeReferenceType::X L_0022: ldloc.3 L_0023: stloc.1 L_0024: ldloc.0 L_0025: call void Program::TryValueType(valuetype SomeValueType) L_002a: ldloc.1 L_002b: call void Program::TryReferenceType(class SomeReferenceType) What I cannot figure out from this code is this: Where are all those local variables mentioned in the .locals block allocated? How are they allocated? How are they freed? Why are so many anonymous local variables needed and copied to-and-fro only to initialize my two local variables rt and vt?

  • Is there a way to pass a regex capture to a block in Ruby?

    - by Gordon Fontenot
    I have a hash with a regex for the key and a block for the value. Something like the following: { 'test (.+?)' => { puts $1 } } Not exactly like that, obviously, since the block is being stored as a Proc, but that's the idea. I then have a regex match later on that looks a lot like this hash.each do |pattern, action| if /#{pattern}/i.match(string) action.call end end The idea was to store the block away in the hash to make it a bit easier for me to expand upon in the future, but now the regex capture doesn't get passed to the block. Is there a way to do this cleanly that would support any number of captures I put in the regex (as in, some regex patterns may have 1 capture, others may have 3)?

  • How can you pass an object from the form_for helper to a method?

    - by Alex
    So let's say I have a form which is being sent somewhere strange (and by strange we mean, NOT the default route: <% form_for @form_object, :url => {:controller => 'application', :action => 'form_action_thing'} do |f| %> <%= f.text_field :email %> <%= submit_tag 'Login' %> <% end %> Now let's say that we have the method that accepts it. def form_action_thing User.find(????? :email ?????) end My questions are thus: How does can I make the object @form_object available to the receiving method (in this case, form_action_tag)? I've tried params[:form_object], and I've scoured this site and the API, which I have to post below because SO doesn't believe I'm not a spammer (I'm a new member), as well as Googled as many permutations of this idea as I could think of. Nothing. Sorry if I missed something, i'm really trying. How do I address the object, once I've made it accessible to the method? Not params[:form_object], I'm guessing.

  • Is it possible to obtain ASP.NET membership user name after FormsAuth.SignIn ?

    - by Simon_Weaver
    I have some code that is accessing Membership.GetUser() to get the current logged in user. This works fine until I try to access it immediately after logging in with FormsAuth.SignIn(userName, false); However I noticed that neither Membership.GetUser() nor User.Identity.Name is updated with the newly logged in user until a new request (I assume its reading directly from the Request cookies). This however kind of screws up my logic that accesses Membership.GetUser() becasue it introduces a special case. Question: is there a way to read the current logged in user with ASP.NET membership immediately after logging in. Or will I have to introduce my own abstraction layer to allow me to 'set' a user as being logged in ? (This is in an AJAX request - so i'd rather not do a redirect).

  • How i pass my view to nib at run time(Dynamically) in viewController class?

    - by Rajendra Bhole
    Hi, I want to create viewController class programmatically in which the view of nib file of viewController is not fixed. I have a UntitledViewController class that contains 4 UIButtons: -(IBAction)buttonPressed:(id)sender{ if((UIButton *)sender == button1){ tagNumber = button1.tag; NewViewController *newVC = [[NewViewController alloc] init]; //newVC.tagN [self.navigationController pushViewController:newVC animated:YES]; NSLog(@"Button Tag Number:- %i", tagNumber); } if((UIButton *) sender == button2){ tagNumber = button2.tag; NewViewController *newVC = [[NewViewController alloc] init]; [self.navigationController pushViewController:newVC animated:YES]; } if((UIButton *) sender == button3){ tagNumber = button3.tag; NewViewController *newVC = [[NewViewController alloc] init]; [self.navigationController pushViewController:newVC animated:YES]; } if((UIButton *) sender == button4){ int x = tagNumber; tagNumber = button4.tag; NewViewController *newVC = [[NewViewController alloc] init]; newVC.untitledVC = self; [self.navigationController pushViewController:newVC animated:YES]; } } When I will click any one of the UIButtons, I want to create a new NewViewController class with button tag property but without fixed nib file. In NewViewController's loadView event I want to fix the view of the nib of NewViewController class using UIButton's tag property (In NewViewController.xib I'm creating 4 UIViews named view1, view2, view3 and view4). -(void)loadView{ [super loadView]; CGRect frame = CGRectMake(0, 0, 320, 480); UIView *newView = [[UIView alloc] initWithFrame:frame]; newView.tag = untitledVC.tagNumber; self.view1 = newView; } Now I want that when I click button1 the NewViewController will be generated with view1 and when I click button2 the NewViewController will be generated with view2 and so on with different implementation. Thanks.

  • How to pass a file (read from Java) most effectively to a native method?

    - by soc
    Hi, I have approx. 30000 files (1MB each) which I want to put into a native method, which requires just an byte array and the size of it as arguments. I looked through some examples and benchmarks (like http://nadeausoftware.com/articles/2008/02/java_tip_how_read_files_quickly) but all of them do some other fancy things. Basically I don't care about the contents of the file, I don't want to access something in that file or the byte array or do anything else with it. I just want to put a file into a native method which accepts an byte array as fast as possible. At the moment I'm using RandomAccessFile, but that's horribly slow (10MB/s). Is there anything like byte[] readTheWholeFile(File file){ ... } which I could put into native void fancyCMethod(readTheWholeFile(myFile), myFile.length()) What would you suggest?

  • How to pass a member function to a function used in another member function?

    - by Tommaso Ferrari
    I found something about my problem, but I don't already understand very well. I need to do something like this: class T{ double a; public: double b; void setT(double par){ a=par; }; double funct(double par1) { return par1/a; } void exec(){ b=extfunct(funct, 10); } } double extfunct(double (*f)(double),double par2){ return f(par2)+5; } Operation and function are only for example, but the structure is that. The reason of this structure is that I have a precostituited class which finds the minimum of a gived function (it's extfunct in the example). So I have to use it on a function member of a class. I understood the difference between pointer to function and pointer to member function, but I don't understand how to write it. Thanks, and sorry for the poor explanation of the problem.

  • MySQL: Query to obtain recipes using all given ingredients.

    - by John_A
    hi I have the following simplified tables: CREATE TABLE recipe(id int, name varchar(25)); CREATE TABLE ingredient(name varchar(25)); CREATE TABLE uses_ingredient(recipe_id int, name varchar(25)); I want to make a query that returns all id's of recipes that contain both Chicken and Cream. I have tried SELECT recipe_id FROM uses_ingredient INNER JOIN (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id) >= (SELECT COUNT(*) FROM theme); which gives me :"ERROR 1248 (42000): Every derived table must have its own alias" and is probably wrong too. Next I tried SELECT recipe_id FROM (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") AS t INNER JOIN uses_ingredient USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id)>= (SELECT COUNT(*) FROM t); which gives "ERROR 1146 (42S02): Table 'recipedb.t' doesn't exist" I want to avoid creating temporary tables including using ENGINE=MEMORY.

  • PHP Postgres constraint violation - can I get the constraint name somehow?

    - by RnR
    We have a web application talking to a Postgres SQL database at work - I've set up many constraints on the server to keep data consistent but we have problems with reporting nicely what it is that prevents the user from entering his (invalid) data at a given moment. The only thing we can get is "Constraint violation" but that isn't very descriptive, from perl or directly from PGAdmin we get nice info as to which constraint caused the failure (the constraint's name) - is there a way to do the same in PHP? We're able to upgrade PHP or use a different db access module if it would help so I'm interested in knowing if it's possible to do using any way that you could safely recommend.

  • What do you name your files when using MVC?

    - by sprugman
    When using the MVC pattern, which I'm not terribly experienced with, I find myself naming things like this: /app/views/widget.php /app/models/widget.php /app/controllers/widget.php That appeals to me because it's easy to find associated classes, and I lean towards shorter names when practical. However, when I'm looking in my IDE, I see three different files called widget.php, which is confusing. I'm tempted to add "_v", "_c", "_m" or something to each name. How do you handle this? FWIW, I'm using CodeIgniter at the moment, and I don't know if there are any special benefits to using a particular convention, or any standard practices. Regardless, I'm intersted in the best-practices from various platforms.

  • In Django, using __init__() method of non-abstract parent model to record class name of child model

    - by k-g-f
    In my Django project, I have a non-abstract parent model defined as follows: class Parent(models.Model): classType = models.CharField(editable=False,max_length=50) and, say, two children models defined as follows: class ChildA(Parent): parent = models.OneToOneField(Parent,parent_link=True) class ChildB(Parent): parent = models.OneToOneField(Parent,parent_link=True) Each time I create an instance of ChildA or of ChildB, I'd like the classType attribute to be set to the strings "ChildA" or "ChildB" respectively. What I have done is added an _ _ init_ _() method to Parent as follows: class Parent(models.Model): classType = models.CharField(editable=False,max_length=50) def __init__(self,*args,**kwargs): super(Parent,self).__init__(*args,**kwargs) self.classType = self.__class__.__name__ Is there a better way to implement and achieve my desired result? One downside of this implementation is that when I have an instance of the Parent, say "parent", and I want to get the type of the child object linked with "parent", calling "parent.classType" gives me "Parent". In order to get the appropriate "ChildA" or "ChildB" value, I need to write a "_getClassType()" method to wrap a custom sql query.

  • [VB.NET] Same name methods in different modules cause ambiguity.

    - by smwikipedia
    I have 2 modules. Each contains a Sub with the same name. See below: Module moduleA Public Sub f(ByVal arg1 As myType) Console.WriteLine("module A") End Sub End Module Module moduleB Public Sub f(ByVal arg1 As myType, ByVal arg2 As Boolean) Console.WriteLine("module B") End Sub End Module But the compiler complains that there's ambiguity between moduleA and moduleB. How could this be? I have totally different signatures. However, if I put the 2 methods into the same module, there's no ambiguity at all. Could someone tell me why? Many thanks.

  • Can't pass and retrieve CharSequence to another activity using intent.getExtras() method.

    - by vt
    Activity 1: Intent i = new Intent(this, Activity2.class); CharSequence btText = btButton.getText(); i.putExtra(BUTTON_TEXT, btText); startActivityForResult(i, ACTIVITY_SETTINGS); Activity 2: in onCreate: Bundle extras = getIntent().getExtras(); if (extras != null) { mButtonText = extras.getCharSequence(Activity1.BUTTON_TEXT); } The resulting CharSequence is not what was passed, it's something like "(id=830066506776)" instead. This works: CharSequence test2 = getIntent().getCharSequenceExtra(Activity1.BUTTON_TEXT); What is wrong with getExtras approach? This is what they used in Notepadv3 example. This is for Android 2.1.

  • How to pass an object from a Frame to another Frame in a Windows 8 Style App

    - by Mythul
    I have problem that i just cant figure out right now. I am trying to develop a Windows-8 style app and im stuck implementing this functionality. I have a MainWindow which contains a ListBox and a Button (lets say addButton). When i click the button i navigate to a new page, lets say AddCustomerPage with this.Frame.Navigate(typeof (AddCustomerPage)); AddCustomerPage has 1 textBox and 1 button (lets say doneButton. When i click the button i want the string in the textBox to be added to the ListBox on the previous page. This is my current functionality: 1. MainWindow is created. Click addButton AddCustomer page is created. MainWindow is destroyed(problem). Click doneButton A MainWindow object is created with a ListBox with 1 item. Repeat the add process, i always get a MainWindow with a ListBox with 1 item. Thanks for the help. Here is the code: public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); this.brainPageController = new PageController(); // add items from the List<String> to the listBox listGoals.ItemsSource = brainPageController.GetListGoals(); } protected override void OnNavigatedTo(NavigationEventArgs e) { var parameter = e.Parameter as String; // a simple controller that adds a string to a List<string> brainPageController.AddGoal(parameter); } private void addButton_Click(object sender, RoutedEventArgs e) { this.Frame.Navigate(typeof (GoalsInfo)); } // VARIABLES DECLARATION private PageController brainPageController; } public sealed partial class GoalsInfo : WinGoalsWIP.Common.LayoutAwarePage { public GoalsInfo() { this.InitializeComponent(); this.brainPageController = new PageController(); } protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState) { } protected override void SaveState(Dictionary<String, Object> pageState) { } private void Button_Click_1(object sender, RoutedEventArgs e) { brainPageController.AddGoal(nameTextBox.Text); this.Frame.Navigate(typeof(MainPage), nameTextBox.Text); } // VARIABLES DECLARATION PageController brainPageController; }
